5. I use "glxgears -info" to test the performance. However ,the
performance is so bad ! It seems no ati driver at all!

A, glxgears is not a benchmark! :)
B, It is probably working, but vsync'ed by default. Try setting the
environment variable vblank_mode=0 before running glxgears. Or configure
this in ~/.drirc
I tried with the setting of vblank_mode = 0
mdl@114-212-83-40:~$ vblank_mode=0 glxgears
ATTENTION: default value of option vblank_mode overridden by environment.

This test is very good !But the gnome animation is still slow, so I
think maybe my computer's hardware(especially my Card) is out of date!
What do you think of this result ?
Is this kind of testing a benchmark?
